The 36-year-old was gunned down as he accompanied Siobhan Phillips, 21, to collect her belongings from a house she shared with dissident republican suspect Adrian Crevan Mackin.

Thousands of participants and spectators took to the streets for Dublin's flagship race meeting, which began at Fitzwilliam Square this morning.

Ethiopian and Ukrainian athletes won the men's and women's races.

As record numbers of runners wound their way through the city in damp and blustery conditions, the fastest man was Alemu Gemechu of Ethiopia in a time of two hours and 14 minutes.

Nataliya Lehonkova from Ukraine won the women's race in a time of two hours and 31 minutes.

Almost 11,000 Irish and more than 4,000 international competitors from 62 countries took part in the race - with the vast majority completing the 36th running of the marathon before bad weather moved in.

It is also expected to be the last time the race is run on the October bank holiday Monday, with organisers hoping to reschedule it to the Sunday.

The switch is regarded as testament to its popularity and designed to attract more international runners and allow competitors to make the most of the long weekend.

In total, 15,216 runners registered to take part.

Patrick Monahan from Naas, Co Kildare, won the wheelchair race in a time of one hour and 43 minutes.

The national titles were claimed by primary school teacher Sean Hehir, who was competing to secure qualification for the Rio Olympics, and Pauline Curley, from Tullamore Harriers.

In 2013, Hehir was first Irish man to win the Dublin Marathon since John Treacy in 1993.
